In this problem of functions of several variables we have to sketch the graph of the function which is r of xy is equals to x minus y.
00:12
So this term can be written as z is equals to x minus y.
00:15
So first step is to find xy and z intercept.
00:18
So first we would find x intercept.
00:21
For finding x intercept we have to put y and z both are equal to 0.
00:25
So putting both term is equal to 0 we get also x is equal to 0.
00:28
So, now from this equation you can see we have to find also y intercept.
00:35
So for finding y intercept we have to put x and z both equals to 0.
00:38
That means y is also equals to 0 similarly z intercept.
00:45
We have to put x and y both is equal to 0 so we get z is equal to 0.
00:50
So we have x intercept as 0 0 0, 0, 0 and z intercept as again 0 0 .0.
00:58
So, we have only one point...
